DumpsterAlwaysON is not working for a 2003 Client on Exchange 2010

I have a user that is using Outlook Client 2003, but is on an exchange 2010 sever.
She already has the registry hack for dumpsteralwayson with a value of 1, yet she cannot recover deleted items from her deleted items, or any other folder. She receives error message: The command is not availble. See the program documentation about how to use this extension. Any ideas on how to resolve this issue.

To resolve this problem, quit Outlook, rename the Resiliency registry key, and then restart Outlook. To do this, follow these steps.
